Working machine

A working machine comprising:

• a machine body;
• a traveling device to support the machine body such that the machine body is allowed to travel;
• an operating lever to operate the traveling device;
• and
• an operation sensor to detect an operation of the operating lever;
• wherein
• the operating lever includes a lever portion, a support shaft portion to rotate in a circumferential direction as the lever portion is pivoted, and a sensor bracket to support the operation sensor;
• the operation sensor includes a magnet, and a switch to be switched between an ON state and an OFF state in response to the magnet approaching or moving away from a predetermined detection position;
• the machine body includes a sensor mount frame to support the sensor bracket;
• the sensor bracket includes:
• a first bracket attached to an outer periphery of the support shaft portion to support the magnet;
• a second bracket to attach the switch thereto;
• and
• a third bracket to connect the second bracket to the sensor mount frame and support the switch at a position where the switch is allowed to detect the magnet at or in a vicinity of the detection position;
• and
• the second bracket is connected to the third bracket such that the second bracket is allowed to change a position thereof in a first direction along which the second bracket approaches and moves away from the magnet.
